Description

Technical Field

[0001] This invention relates to the field of underground mine cooling technology, and in particular to a cooling and dehumidification system for mine tunnels. Background Technology

[0002] Cooling and dehumidifying mine tunnels is a core technology for deep well mining, ensuring safe production, and improving the working environment. Its main function is to control the working area environment within a comfortable range of temperature 26~28℃ and relative humidity 60%~80%, solving problems such as heatstroke among personnel, equipment corrosion, electrical failures, and decreased efficiency caused by high temperature and high humidity.

[0003] Related technology can be found in Chinese patent application CN119641418A, which discloses a mine local cooling and dehumidification device, including a base frame, a box on the base frame, a water tank inside the box, a heat exchange tube inside the water tank, a semiconductor cooler penetrating through the side wall of the water tank, a heat dissipation cavity in the part of the box outside the water tank, an air inlet and an air outlet on the box, the air inlet being connected to one end of an air supply pipe, and the air outlet being connected to one end of an air exhaust pipe; one end of the heat exchange tube is connected to a dust collection device pipe, the dust collection device is connected to an air inlet pipe, and the air inlet pipe has an air inlet hole; the other end of the heat exchange tube is connected to the inlet pipe of an air pump, and the outlet of the air pump is connected to an airflow transmission component pipe; the airflow transmission component includes a shell, an air inlet on the side of the shell, a T-shaped tube penetrating and rotatably mounted on the axis, an air outlet on the T-shaped tube, and a fan blade and an airflow inlet on the T-shaped tube inside the shell.

[0004] Regarding the aforementioned technologies, the effectiveness of the cooling and dehumidification system depends on the installation and arrangement of the exhaust and supply ducts. However, in order to keep the airflow at a low temperature, the existing cooling systems using a dual-duct system of exhaust and supply ducts are often inconvenient for maintenance and inspection due to the long length of the ducts. Therefore, the ducts in mines are usually made of metal pipes. For some narrow mine tunnels, it is inconvenient to install and debug ventilation ducts. As a result, the existing cooling systems are not suitable for the complex underground mine environment. Summary of the Invention

[0005] To be applicable to mine tunnels with complex terrain, this application provides a cooling and dehumidification system for mine tunnels.

[0006] This application provides a cooling and dehumidification system for mine tunnels, which adopts the following technical solution: A cooling and dehumidification system for mine tunnels includes a main body of equipment. Inside the main body of the equipment is a gas circulation system and a refrigeration system. The gas circulation system has an inlet pipe and an outlet pipe. In operation, external gas flows along the inlet pipe to the outlet pipe, and the flow path passes through the refrigeration system, where it is cooled. The system also includes: Several first hoses are connected to the air outlet pipe, and each first hose has an insulation layer on its inner side; the end of the first hose away from the air outlet pipe is set as an exhaust section, and the exhaust section has several exhaust ports along its length. Several fixed seats are arranged along the length of the exhaust section and correspond one-to-one with the exhaust port. Several anchor bolts are installed on the fixed seats and anchored to the inner wall of the mine through the anchor bolts. The exhaust section is provided with a connector that connects to the fixed seats. The fixed seats support the exhaust section and are provided with air guide nozzles that correspond to the exhaust ports. Cooling airflow is delivered to the outside through the air guide nozzles.

[0007] By adopting the above technical solution, when the gas circulation system inside the main body of the equipment is working, the gas in the mine enters the main body of the equipment through the inlet pipe, is cooled by the refrigeration system, and then flows into all the first hoses through the outlet pipe. The fixing base is installed in the preset position by anchor bolts, so that the fixing base uses the connecting parts to suspend and support the exhaust section of the first hose. The installation position of the fixing base can be adjusted according to actual needs. When the airflow enters the exhaust section, it enters the air guide nozzle through the exhaust port and is sprayed out into the mine. The positions of the air guide nozzle and the exhaust port can be adjusted according to actual needs, thereby adapting to the complex underground environment. Furthermore, several cold air outlets are set, so that cooling can be carried out at multiple different locations in the same area, which helps to improve the cooling effect and the uniformity of cooling.

[0008] Optionally, several second hoses are provided, and all second hoses are connected to the air inlet pipe. Several support rings are arranged along the axial direction on the inner side of the second hoses. All support rings cooperate to restrict the radial deformation of the second hoses. Several air inlets are arranged along the length direction on the side of the second hoses away from the air inlet pipe. In the working state, the air inlets of the second hoses correspond to the exhaust ports of the first hoses. When the gas circulation system is working, the external airflow flows from the exhaust port to the air inlet. Several suspension components are provided on the second hoses, and the second hoses are fixed to the inner wall of the mine through the suspension components.

[0009] By adopting the above technical solution, the suspension component fixes the second hose to the inner wall of the mine. When the second hose draws in gas from inside the mine through the air inlet, the air inlet and the exhaust outlet are set opposite each other, thereby forming a directional airflow in the mine, which helps to further accelerate the gas flow and improve the cooling effect. The support ring supports the second hose and reduces the probability that it will be excessively deformed during the air intake process, thus affecting the air intake effect.

[0010] Optionally, the suspension component includes a fixing ring, a retaining ring, and an anchor rod. The retaining ring is fixedly connected to a filter screen corresponding to the air inlet. When the filter screen is located inside the air inlet, the retaining ring is in contact with the outer wall of the second hose. The fixing ring is located on the side of the second hose away from the retaining ring, and the retaining ring is detachably connected to the fixing ring by bolts. The anchor rod is set on the fixing ring and suspends the fixing ring on the inner wall of the mine.

[0011] By adopting the above technical solution, the retaining ring supports the filter screen. When the filter screen is inserted into the air inlet, the position of the retaining ring and the second hose is relatively fixed. The fixing ring is connected to the retaining ring by bolts. Under the fixing action of the anchor rod, the fixing ring and the retaining ring cooperate to fix the second hose to the inner wall of the mine.

[0012] Optionally, the main body of the equipment is also provided with a water removal section. The air inlet pipe and the air outlet pipe are both connected to the water removal section. When the gas flows in the main body of the equipment, it passes through the water removal section, so that the water removal section removes the moisture in the gas.

[0013] By adopting the above technical solution and adding a dehumidification section, after the gas inside the mine is drawn into the main body of the equipment, the dehumidification section absorbs the moisture in the gas and discharges the dried gas, thereby completing the gas dehumidification process.

[0014] Optionally, the exhaust section includes several alternately arranged connecting sections and adjusting sections, wherein the outer side of the connecting section is provided with an opposing mounting plane and an exhaust plane, the exhaust port is opened on the exhaust plane, the connecting member includes a first clamping plate and a second clamping plate, the first clamping plate is fixedly connected to the mounting plane, and the first clamping plate has a first groove opened in the transverse direction, the fixed seat has a first fixed plate that engages with the first groove, the fixed seat has a first moving block, the first moving block is slidably connected to the fixed seat in a direction perpendicular to the mounting plane, the fixed seat has a positioning screw for positioning the first moving block, the second clamping plate is provided at the connecting plane, the second clamping plate has a second groove opened in the transverse direction, and the first moving block is slidably connected to the second fixed plate that engages with the second groove.

[0015] By adopting the above technical solution, the adjustment part facilitates the adjustment of the angle between two adjacent connecting parts, making it suitable for different installation conditions. Both the mounting plane and the connecting plane are easy to add external structures to. When the first fixing plate mates with the first slot, the first slot is fixed on the first fixing seat, thereby fixing the mounting plane. When the second fixing plate mates with the second slot, the connecting block is connected to the second slot. By adjusting the position of the moving block, the distance between the mounting plane and the connecting plane can be adjusted. After the moving block is positioned by the positioning screw, the connecting part is fixed.

[0016] Optionally, the fixed base is rotatably connected to a movable plate. In the working state, the movable plate is located at the mounting plane, and the rotation axis of the movable plate is perpendicular to the mounting plane. The air guide nozzle is set on the movable plate and is slidably connected to the movable plate along the moving direction of the moving block. When the movable plate rotates, it drives the air guide nozzle through the exhaust port. The air guide nozzle is provided with a plug-in part. When the plug-in part is inserted into the exhaust port, it communicates with the exhaust port. The movable plate is provided with a positioning screw for locking the air guide nozzle.

[0017] By adopting the above technical solution, the movable plate supports and positions the air guide nozzle. When the movable plate flips, it moves the air guide nozzle to avoid or approach the connecting part. After the air guide nozzle is connected to the exhaust port through the plug-in part, the movement of the air guide nozzle is locked by the positioning screw, thus positioning the air guide nozzle. The air guide nozzle and the second flexible hose are set separately, which helps to simplify the structure of the second flexible hose and facilitates its movement and storage.

[0018] Optionally, the end of the air guide nozzle away from the plug is designated as the exhaust end, the opening of the exhaust end is arranged along the axis of the exhaust part, a filter screen is provided inside the exhaust end, and an air guide plate is rotatably connected to the inner side of the exhaust end, and the rotation axis of the air guide plate is the same as the direction of the exhaust end opening.

[0019] By adopting the above technical solution, gas enters through the plug-in end and exits from the exhaust end, while the filter screen prevents external debris from entering the air guide nozzle. The direction of cold air exhaust can be adjusted by changing the rotation angle of the air guide plate, further improving its adaptability to complex environments.

[0020] Optionally, a third flexible hose is provided at the middle position of the air guide nozzle, and the plug is fixedly connected to the third flexible hose. The movable plate includes a rotating part, a flipping part, and a locking member. The rotating part is rotatably connected to the fixed base, and the rotation axis is parallel to the moving direction of the moving block. The flipping part is rotatably connected to the rotating part, and the rotation axis of the flipping part is perpendicular to the rotation axis of the rotating part. The air guide nozzle is connected to the flipping part and moves synchronously with the flipping part. The locking member is provided on the flipping part, and the fixed base cooperates with the locking member to restrict the rotation of the flipping part and the rotating part.

[0021] By adopting the above technical solution, the rotating part supports the flipping part. When the plug-in part is connected to the exhaust port, the third hose is deformed by rotating the flipping part, which can adjust the orientation of the air guide nozzle and thus adjust the air jet direction of the air guide nozzle again. This is suitable for complex working conditions.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the gas circulation system inside the main body of the equipment is working, the gas in the mine enters the main body of the equipment through the inlet pipe. After being cooled by the refrigeration system, it flows into all the first hoses through the outlet pipe. The fixing base is installed in the preset position by anchor bolts, so that the fixing base uses the connecting parts to suspend and support the exhaust section of the first hose. The installation position of the fixing base can be adjusted according to actual needs. When the airflow enters the exhaust section, it enters the air guide nozzle through the exhaust port and is sprayed out into the mine. The positions of the air guide nozzle and the exhaust port can be adjusted according to actual needs to adapt to the complex underground environment. Furthermore, several cold air outlets are set up to cool multiple different locations in the same area, which helps to improve the cooling effect and the uniformity of cooling. 2. The suspension component fixes the second hose to the inner wall of the mine. When the second hose draws in gas from inside the mine through the air inlet, the air inlet and the exhaust outlet are set opposite each other, thereby forming a directional airflow in the mine, which helps to further accelerate the gas flow and improve the cooling effect. The support ring supports the second hose and reduces the probability of it being excessively deformed during the air intake process, which affects the air intake effect. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a cooling and dehumidification system for mine tunnels. Example

[0032] Reference Figure 1 and Figure 2 A cooling and dehumidification system for mine tunnels includes a main body 1. The main body 1 houses an air circulation system and a refrigeration system. The air circulation system can be a fan, while the refrigeration system uses an evaporator; both are existing technologies and will not be described in detail here. A control center is also located within the main body 1, connected to and controlling the start and stop of the air circulation and refrigeration systems. Specifically, the control center can be a PLC system. Multiple casters are installed below the main body 1 to facilitate movement and position adjustment by personnel.

[0033] Reference Figure 1 and Figure 2 The air circulation system includes an inlet pipe 21 and an outlet pipe 22, both installed on the main body 1 of the equipment. When the fan is operating, the inlet pipe 21 absorbs gas from the mine, and the gas is ejected from the outlet pipe 22. Furthermore, a dewatering section is installed inside the main body 1, through which gas passes as it flows within the equipment body 1. The dewatering section utilizes existing dewatering and drying mechanisms, specifically including a condenser and a water separator. Other common dewatering equipment from the prior art can also be used, but will not be elaborated upon here.

[0034] Reference Figure 1 and Figure 2 The air inlet duct is connected to multiple second flexible hoses 6, all of which are detachably connected to the air inlet duct via pipe connectors 33. The second flexible hoses 6 are made of a deformable material, such as rubber. Furthermore, the cross-section of the second flexible hose 6 is annular for easy coiling and storage. Multiple support rings 61, made of elastic material, are arranged along the axial direction inside the second flexible hose 6 to support it.

[0035] Reference Figure 1 and Figure 2 The second flexible hose 6 has multiple air inlets 62 at the end away from the air inlet pipe. The multiple air inlets 62 are arranged along the length of the second flexible hose 6, and the second flexible hose 6 is provided with multiple suspension members 7 corresponding to the exhaust ports. The suspension member 7 includes a fixing ring 71, a retaining ring 72, and an anchor rod 73. The fixing ring 71 and the retaining ring 72 are located on both sides of the second flexible hose 6, and the fixing ring 71 and the retaining ring 72 are detachably connected by bolts.

[0036] Reference Figure 1 and Figure 2A filter screen 721 is installed on the retaining ring 72, located inside the air inlet 62 and fitting against the inner wall of the air inlet 62. At this time, the retaining ring 72 and the second hose 6 are in a mutually positioned state. Mounting plates are installed on both sides of the fixing ring 71, and the anchor rod 73 passes through the mounting plates and is anchored to the inner wall of the mine. At this time, the fixing ring 71 and the retaining ring 72 cooperate to suspend and fix the second hose 6. When the air circulation system is working, the air intake pipe 21 draws air from the mine through the air inlet 62 on the second hose 6. During this process, the filter screen 721 prevents external debris from entering the second hose 6.

[0037] Reference Figure 1 and Figure 3 Multiple first hoses 3 are connected to the exhaust pipe 22, and the first hoses 3 are also detachably connected to the exhaust pipe 22 via pipe connectors 33. The pipe connectors 33 can be common threaded joints, and the number of first hoses 3 and second hoses 6 can be set according to actual needs. The gas in the mine is cooled by the refrigeration system and flows into different first hoses 3 along the exhaust pipe 22. The inner side of the first hose 3 is provided with a heat insulation layer, so that the cold air is kept at a low temperature during the flow.

[0038] Reference Figure 1 and Figure 4 The first flexible hose 3 has an exhaust end 53 at the end furthest from the outlet pipe 22. The exhaust end 53 includes multiple alternately arranged connecting parts 311 and adjusting parts 312. The adjusting parts 312 have a circular cross-section, which facilitates bending and adjustment when the hose is extended. The connecting parts 311 have a rectangular cross-section, so that the outer sides of the connecting parts 311 form mutually parallel and opposing mounting planes and exhaust planes. An exhaust port 321 is provided at the exhaust plane, and a support frame is fixed around the connecting parts 311 along the circumference of the exhaust port 321. Both the support frame and the exhaust port 321 are radially arranged along the second flexible hose 6, thereby reducing the interference of the support frame on the folding and storage of the second flexible hose 6.

[0039] Reference Figure 3 and Figure 4 A connector 33 is provided on the connecting part 311. The connector 33 includes a first clamping plate 331 and a second clamping plate 332. The first clamping plate 331 is fixedly connected to the mounting plane, and the second clamping plate 332 is fixedly connected to the exhaust plane and is also fixedly connected to the support frame. The second clamping plate 332 has a first clamping groove 333 radially along the first flexible hose 3, and the second clamping plate 332 also has a second clamping groove 334 radially along the first flexible hose 3.

[0040] Reference Figure 3 and Figure 4The second flexible hose 6 is provided with a fixing seat 4 corresponding to the connecting part 311. The fixing seat 4 is provided with multiple anchor bolts 41. The anchor bolts 41 pass through the fixing seat 4 and are anchored to the inner wall of the mine, so that the fixing seat 4 is fixed to the inner wall of the mine. Two sets of guide rods 44 are vertically fixed on the side of the fixing seat 4 away from the inner wall of the mine. One set of guide rods 44 is slidably connected to a moving block 43 along the length direction, and the other set of guide rods 44 is slidably connected to a positioning block 48.

[0041] Reference Figure 4 and Figure 5 A spring is provided between the positioning block 48 and the corresponding guide rod 44. The spring applies a pushing force to the positioning block 48, bringing it closer to the fixing seat 4. When installing the connecting part 311, the mounting surface of the mounting part is brought close to the fixing seat 4. A fixing plate 42 that matches the slot 333 is slidably connected to the fixing seat 4. The operator can slide the fixing plate 42 so that it enters the slot 333, thus connecting the fixing plate 42 and the slot 331. A positioning bolt is threaded onto the fixing plate 42. When the positioning bolt is tightened, it abuts against the fixing seat 4, thereby locking the positioning of the fixing plate 42 and initially connecting the connecting part 311 to the fixing seat 4.

[0042] Reference Figure 4 and Figure 5 The movable block 43 is slidably connected to the fixed plate 45 in the same direction as the fixed plate 42, and the fixed plate 45 is adapted to the slot 334. One end of the fixed plate 45 is fixed with a pin, and the positioning block 48 is provided with a positioning groove 481 adapted to the pin. After the fixed plate 45 is moved and the pin on the fixed plate 45 is inserted into the positioning groove 481, the fixed plate 45 is connected to the slot 332.

[0043] Reference Figure 4 and Figure 5 A positioning screw 46 parallel to the guide rod 44 is provided on the fixed base 4. The positioning screw 46 is rotatably connected to the fixed base 4 around its own axis, and the positioning screw 46 is located at the end of the guide rod 44 away from the fixed base 4. The moving block 43 has a threaded hole 431 adapted to the positioning screw 46. The moving block 43 is moved away from the fixed plate 42 until the positioning screw 46 is threaded into the threaded hole 431, thereby positioning the moving block 43. At this time, the connecting part 311 is in a fully supported state. The position of the moving block 43 can be adjusted by rotating the positioning screw 46, so that the moving block 43 drives the second clamping plate 332 to move closer to or away from the first clamping plate 331, thereby deforming the connecting part 311 and adjusting the internal diameter of the connecting part 311.

[0044] Reference Figure 4 and Figure 6A movable plate 8 is provided on the fixed base 4. The movable plate 8 is located at the end of the guide rod 44 away from the fixed base 4. The movable plate 8 includes a rotating part 81, a flipping part 82, and a locking member 83. The rotating part 81 is rotatably connected to the guide rod 44, and the axis of rotation is parallel to the guide rod 44. The flipping part 82 is rotatably connected to the rotating part 81. During the rotation of the rotating part 81, the flipping part 82 is driven to swing, so that the flipping part 82 avoids or approaches the exhaust plane of the connecting part 311.

[0045] Reference Figure 4 and Figure 6 The locking element 83 is located at the end of the flipping part 82 away from the rotating part 81. The locking element 83 includes a rotating block 831 and a clamping block 832. The flipping part 82 is fixedly connected to a rotating shaft 821, and the flipping part 82 rotates around the axis of the rotating shaft 821. The rotating shaft 821 passes through the rotating block 831 and is rotatably connected to the rotating block 831. The clamping block 832 is slidably connected to the rotating block 831 radially along the rotating shaft 821, and the clamping block 832 is rotatably connected to a clamping bolt 834. The rotation axis 821 of the clamping bolt 834 is parallel to the direction of movement of the clamping block 832. Multiple adjustment grooves are arranged circumferentially on the outer side of the rotating shaft 821. The clamping block 832 is fixedly connected to a limiting block 833 corresponding to the adjustment groove. When the clamping block 832 approaches the rotating block 831, the limiting block 833 is inserted into the adjustment groove, thereby locking the relative rotation between the flipping part 82 and the rotating block 831.

[0046] Reference Figure 4 and Figure 6 An air guide nozzle 5 is provided on the flipping part 82, and the air guide nozzle 5 is arranged sequentially along the length direction as an exhaust end 53, a middle part, and a plug-in part 51. The middle part is a third flexible hose 52 made of a deformable material, such as rubber. The exhaust end 53, the third flexible hose 52, and the plug-in part 51 are connected in sequence. The flipping part 82 has an opening 823, and the third flexible hose 52 is located inside the opening 823 and slides within the opening 823 along the length direction.

[0047] Reference Figure 4 and Figure 6 Furthermore, both the exhaust end 53 and the insertion part 51 are made of rigid materials. After the connection part 311 is installed, the movable plate 8 is rotated until the insertion part 51 of the air guide nozzle 5 is aligned with the exhaust port. The air guide nozzle 5 is moved along the movable opening 823 until the insertion part 51 is inserted into the exhaust port, completing the connection between the air guide nozzle 5 and the connection part 311. The cold air flowing along the first flexible hose 3 enters the air guide nozzle and is discharged from the exhaust end 53. The opening of the exhaust end 53 is set along the axial direction of the connection part 311, which helps to increase the diffusion trajectory of the cold air. A positioning screw is provided on the flip part 82. When the positioning screw is tightened, the positioning screw abuts against the exhaust end 53, thereby locking the exhaust end 53 and the flip part 82.

[0048] Reference Figure 4 and Figure 6 When the rotating flipping part 82 is rotated, it drives the exhaust part 31 to rotate, thereby adjusting the orientation of the exhaust part 31 to suit different working environments. A locking plate 47 is fixedly connected to the end of the guide rod 44 away from the fixed base 4, and the locking plate 47 has a threaded hole 471 corresponding to the clamping bolt 834. When the insertion part 51 is facing the exhaust port, the clamping bolt 834 is facing the threaded hole 471. At this time, the clamping bolt 834 is rotated until the clamping bolt 834 and the threaded hole 471 are threadedly engaged. When the clamping bolt 834 is screwed in, it drives the clamping block 832 to approach the rotating shaft 821 until the limit block 833 is inserted into the adjustment groove and locks the rotating shaft 821 and the rotating block 831. At this time, the entire movable plate 8 is in a fixed state to support and fix the air guide nozzle.

[0049] Reference Figure 4 and Figure 6 A filter screen 531 is provided inside the exhaust end 53 to prevent external debris from entering the first hose 3 along the air guide nozzle. An air guide plate 532 is also provided at the exhaust end 53, located on the side of the filter screen 531 away from the fixed base 4, and is rotatably connected to the exhaust end. The rotation axis of the air guide plate 532 is perpendicular to the rotation axis of the tilting part 82. By adjusting the angle of the air guide plate 532, the operator can guide the airflow and thus adjust the direction of the cold air injection. Different rotation angles between the air guide plate 532 and the tilting part 82 make it suitable for more working conditions.

[0050] The implementation principle of a cooling and dehumidification system for mine tunnels according to an embodiment of this application is as follows: Multiple sets of first flexible hoses 3 and multiple sets of second flexible hoses 6 are installed and adjusted according to actual site conditions, making it suitable for complex underground environments. Furthermore, the exhaust vent 321 and the air inlet 62 are arranged opposite each other. When the air circulation system is working, it drives the airflow within the mine to circulate. Cool air is discharged from the exhaust vent 321 and flows towards the air inlet 62 with other airflows, thus forming a cool airflow that helps improve the cooling effect. Moreover, multiple cool air outlets are provided, thereby creating multiple cooling zones within the same area, further enhancing the cooling effect. The position of the main body 1 and the state of the first flexible hoses 3 and second flexible hoses 6 can all be adjusted and changed according to actual needs, thus adapting to complex underground environments.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
